This particular series of F-150 trucks have already gained notoriety for its collection of oxidized metal. In this instance, the reported excessive corrosion can cause one or both of the fuel-tank support straps to break, leading to a loose or dragging fuel tank. Fuel may then leak out of the tank and start another set of problems.

Thankfully, there haven't been any reports of crashes, fires, injuries, or fatalities. The NHTSA estimates the inquisition could affect around 1.4 million trucks.
